Abstract

Large language models (LLMs) have shown remarkable performance in natural language processing (NLP) tasks. To comprehend and execute diverse human instructions over image data, instruction-tuned large vision-language models (LVLMs) have been introduced. However, LVLMs may suffer from different types of object hallucinations. Nevertheless, LVLMs are evaluated for coarse-grained object hallucinations only (i.e., generated objects non-existent in the input image). The fine-grained object attributes and behaviors non-existent in the image may still be generated but not measured by the current evaluation methods. In this paper, we thus focus on reducing fine-grained hallucinations of LVLMs. We propose \textit{ReCaption}, a framework that consists of two components: rewriting captions using ChatGPT and fine-tuning the instruction-tuned LVLMs on the rewritten captions. We also propose a fine-grained probing-based evaluation method named \textit{Fine-Grained Object Hallucination Evaluation} (\textit{FGHE}). Our experiment results demonstrate that ReCaption effectively reduces fine-grained object hallucination for different LVLM options and improves their text generation quality.

Abstract

The continuous casting mould is the most crucial core component of the continuous casting production line, which undertakes the important tasks of cooling, heat conduction, abrasion resistance and high-precision forming of the billet surface during the high-speed vibration drawing process of the molten steel. Based on the engineering application practice of mould surface protective coatings in domestic steel plants, the advantages, disadvantages and developing trends of electroplated alloy coatings and thermal spray coatings on the surface of mould copper plate were summarized, as well as the main failure forms and formation mechanisms at different locations of mould surface after service under actual working conditions, providing the basis for optimizing the design of coating compositions and corresponding performance in different areas. Moreover, the service results and application advantages of the thermal spraying/vacuum diffusion composite technology developed by the project team in major domestic steel plants were introduced in detail. Finally, it was pointed out that thermal spraying technology will gradually replace electroplating technology and become the core technology of mold surface protection, and high entropy and medium entropy alloy coating has great application potential.

Abstract

Our study addresses two separate but complementary questions for California in the years and decades ahead: 1) what benefits would the emergence of a major offshore wind power sector create for California workers and communities, and what policies might optimize these impacts; and 2) would offshore wind power be a competitive source of renewable energy in comparison to other clean energy sources?

Abstract

Monitoring China's carbon dioxide (CO2) concentration is essential for formulating effective carbon cycle policies to achieve carbon peaking and neutrality. Despite insufficient satellite observation coverage, this study utilizes high-resolution spatiotemporal data from the Orbiting Carbon Observatory 2 (OCO-2), supplemented with various auxiliary datasets, to estimate full-coverage, monthly, column-averaged carbon dioxide (XCO2) values across China from 2015 to 2022 at a spatial resolution of 0.05° via the deep forest model. The 10-fold cross-validation results indicate a correlation coefficient (R) of 0.95 and a determination coefficient (R²) of 0.90. Validation against ground-based station data yielded R values of 0.93, and R² values reached 0.81. Further validation from the Greenhouse Gases Observing Satellite (GOSAT) and the Copernicus Atmosphere Monitoring Service Reanalysis dataset (CAMS) produced R² values of 0.87 and 0.80, respectively. During the study period, CO2 concentrations in China were higher in spring and winter than in summer and autumn, indicating a clear annual increase. The estimates generated by this study could potentially support CO2 monitoring in China. [ABSTRACT FROM AUTHOR]
